Dale Whittaker fb2a962ad4 Store the 'day' of history items to reduce even more calls to localtime
By storing the timestamp of the day in the database we can significantly
reduce the calls to localtime, which should result in a noticible
speedup.

We are changing the database format. For the convenience of the user
the code automatically converts from the old format.
